Windows service running not doing anything

My service is running but it does not do any of the logic i inserted in OnStart,
Also, I am try to log messages to the eventviewer but it does not even get to that part (which i assume is falling before the OnStart..)
Can someone please tell me what i am doing wrong? Thanks,
public partial class DSGService : ServiceBase
{
private static string ftpPath = ConfigurationManager.AppSettings["FtpPath"];
private Timer _timer;
private bool _isRunning;
public DSGService()
{
InitializeComponent();
AppDomain.CurrentDomain.UnhandledException += CurrentDomain_UnhandledException;
}
private void CurrentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e)
{
WriteToEventViewer("error!:" + e.ExceptionObject.ToString());
}
OnStart logic
protected override void OnStart(string[] args)
{
_isRunning = false;
_timer = new Timer
{
AutoReset = true,
Interval = 5000,
};
_timer.Elapsed += new ElapsedEventHandler(this.TimerElapsed);
_timer.Start();
}
code to do things
private void TimerElapsed(object sender, ElapsedEventArgs e)
{
if (_isRunning)
{
WriteToEventViewer("isrunning is true");
return;
}
try
{
_isRunning = true;
WriteToEventViewer("started");
//do things..
WriteToEventViewer("generated!");
}
}
finally
{
_isRunning = false;
WriteToEventViewer("done");
}
}
private void GenerateAndPublishData(ServerData server)
{
try
{
//do things...
}
catch (Exception ee)
{
WriteToEventViewer(string.Format("error: {0}", ee);
}
}
protected override void OnStop()
{
_timer.Stop();
_timer.Dispose();
_timer = null;
}
write to eventviewer
private void WriteToEventViewer(string msg)
{
using (EventLog eventLog = new EventLog("DSGService"))
{
eventLog.Source = "DSGService";
eventLog.WriteEntry(msg, EventLogEntryType.Information, 101, 1);
}
}
}```

This is probably the result of an exception inside the TimerElapsed method, that prevents the timer from restarting. To aviod this, here's what you do:
Set the AutoReset property of your timer to false.
Inside the TimerElapsed event handler, in the finally clause, start the timer again.
This means that even if an exception occured in your TimerElapsed event handler, the timer will start again.

Windows Service Does Not Fire OnStart Event

I have windows service application. But the OnStart event does not fire. Only OnStop event is firing every time I stop the service. What did I miss ?
public partial class Scheduler : ServiceBase
{
private Timer timer1 = null;
public Scheduler()
{
InitializeComponent();
}
protected override void OnStart(string[] args)
{
timer1 = new Timer();
timer1.Interval = 5000;
timer1.Elapsed += new ElapsedEventHandler(this.timer1_Tick);
}
protected override void OnStop()
{
timer1.Enabled = false;
Library.Log(String.Format("Windows service stopped"));
}
private void timer1_Tick(object sender, ElapsedEventArgs e)
{
Library.Log(String.Format("Scheduler service {0}", DateTime.Now));
}
}

OnStart is firing, your timer is not.
You must either do timer1.Start() or timer1.Enabled = true in OnStart for the timer to start firing.
protected override void OnStart(string[] args)
{
Library.Log("Windows service started");
timer1 = new Timer();
timer1.Interval = 5000;
timer1.Elapsed += new ElapsedEventHandler(this.timer1_Tick);
timer1.Start()
}

c# Function work with Timer(AutoFunction)

I do have one checking function that will run once opening the application.
How to make it Auto Function like every 20 seconds run the function?
Main()
{
Checking();
}
public void Checking() // run this function every 20 seconds
{ // some code here
}

You can use the C# Timer class
public void Main()
{
var myTimer = new Timer(20000);
myTimer.Elapsed += new ElapsedEventHandler(OnTimedEvent);
myTimer.Enabled = true;
Console.ReadLine();
}
private static void OnTimedEvent(object source, ElapsedEventArgs e)
{
Console.WriteLine("The Elapsed event was raised at {0}", e.SignalTime);
}

Main()
{
Timer tm = new Timer();
tm.Interval = 20000;//Milliseconds
tm.Tick += new EventHandler(tm_Tick);
tm.Start();
}
void tm_Tick(object sender, EventArgs e)
{
Checking();
}
public void Checking()
{
// Your code
}

Restarting a windows service after a fixed time interval

I am developing a windows service that sends automated e-mail in every 15 minutes. I am using a timer to use the service again after a fixed time interval (15 minutes) but its not working.
namespace Mailer
{
public partial class Mailer : ServiceBase
{
System.Timers.Timer createOrderTimer;
public Mailer()
{
InitializeComponent();
}
protected override void OnStart(string[] args)
{
sendmail(); //function to send email.
createOrderTimer = new System.Timers.Timer();
createOrderTimer.Elapsed += new System.Timers.ElapsedEventHandler(createOrderTimer_Elapsed);
createOrderTimer.Interval = 15000;
createOrderTimer.Enabled = true;
createOrderTimer.AutoReset = true;
createOrderTimer.Start();
}
protected void createOrderTimer_Elapsed(object sender, System.Timers.ElapsedEventArgs args)
{
createOrderTimer.Stop();
ServiceController controller = new ServiceController("Mailer");
controller.Start();
}
protected void sendmail
{
//code to send email.
}
protected override void OnStop() { }
}
}
Initially the email is sent but I want the email sending to be performed in every 15 minutes.

You need to change the code like this
namespace Mailer
{
public partial class Mailer : ServiceBase
{
System.Timers.Timer createOrderTimer;
public Mailer()
{
InitializeComponent();
}
protected override void OnStart(string[] args)
{
createOrderTimer = new System.Timers.Timer();
createOrderTimer.Elapsed += new System.Timers.ElapsedEventHandler(sendmail);
createOrderTimer.Interval = 900000; // 15 min
createOrderTimer.Enabled = true;
createOrderTimer.AutoReset = true;
createOrderTimer.Start();
}
protected void sendmail(object sender, System.Timers.ElapsedEventArgs args)
{
//code to send email.
}
protected override void OnStop() { }
}
}

Windows Service doesn't start based on the interval time

I wrote a windows service to call my class library every 10 mins interval,it works fine when start or restart .once the job done it suppose to re run again every 10 min's that's not happening at all.Am not sure what am missing,some one please identify the correct way.
Here is my code
public partial class Service1 : ServiceBase
{
private Timer _timer;
private DateTime _lastRun = DateTime.Now;
public Service1()
{
InitializeComponent();
}
protected override void OnStart(string[] args)
{
log4net.Config.XmlConfigurator.Configure();
_timer = new Timer(10 * 60 * 1000); // every 10 minutes
_timer.Elapsed += new System.Timers.ElapsedEventHandler(timer_Elapsed);
Shell Distribute= new Shell();
Distribute.Distribute();
}
protected override void OnStop()
{
this.ExitCode = 0;
base.OnStop();
}
private void timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
{
//if (_lastRun.Date < DateTime.Now.Date)
//{
_timer.Stop();
_lastRun = DateTime.Now;
_timer.Start();
//}
}
}
}

Your problem is compare of date if (_lastRun.Date < DateTime.Now.Date) so your code runs once a day.

I agree with Ozgur. It appears that your logic is wrong. You can just stop the timer during the timer_Elapsed event do you logic and restart timers
Something like :
private void timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
{
try{
// stop the timer while we are running the cleanup task
_timer.Stop();
//
// do cleanup stuff
//
}catch (Exception e){
//do your error handling here.
}
finally{
_timer.Start();
}
}
}
Just wrap it with a try catch and finally so you handle exceptions and can make sure the timer is started again. Also please review this link Best Timer for using in a Windows service

Okie Finally i got the answer,why its not working (One of the expert from other forum point out my mistake)
This the code works well based on timer interval.
public partial class Service1 : ServiceBase
{
private Timer _timer;
private DateTime _lastRun = DateTime.Now;
public Service1()
{
InitializeComponent();
}
protected override void OnStart(string[] args)
{
log4net.Config.XmlConfigurator.Configure();
_timer = new Timer(10 * 60 * 1000); // every 10 minutes
_timer.Elapsed += new System.Timers.ElapsedEventHandler(timer_Elapsed);
Shell Distribute= new Shell();
Distribute.Distribute();
_timer.start();//this line was missed in my original code
}
protected override void OnStop()
{
this.ExitCode = 0;
base.OnStop();
}
private void timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
{
//if (_lastRun.Date < DateTime.Now.Date)
//{
try
{
_timer.Stop();
Shell Distribute= new Shell();
Distribute.Distribute();
}
catch(exception ex)
{}
finally
{
_timer.Start();
}
//}
}
}
}
